LMC6482 CMOS Dual Rail-To-Rail Input and Output Operational Amplifier 1 Features 3 Description . 1 Typical Unless Otherwise Noted The LMC6482 device provides a common-mode range that extends to both supply rails. This Rail-To-Rail Rail-To-Rail Input Common-Mode Voltage Range performance combined with excellent accuracy, due (Ensured Over Temperature) to a high CMRR, makes it unique among Rail-To-Rail Rail-To-Rail Output Swing (Within 20-mV of Supply Input amplifiers. The device is ideal for systems, such rail , 100-k Load) as data acquisition, that require a large Input signal Ensured 3-V, 5-V, and 15-V Performance range. The LMC6482 is also an excellent upgrade for circuits using limited common-mode range amplifiers Excellent CMRR and PSRR: 82 dB such as the TLC272 and TLC277.
2 Ultralow Input Current: 20 fA. Maximum dynamic signal range is assured in low High Voltage Gain (R L = 500 k ): 130 dB voltage and single supply systems by the Rail-To-Rail Specified for 2-k and 600- Loads Output swing of the LMC6482 . The Rail-To-Rail Output Power-Good Output swing is ensured for loads down to 600 of the device. Ensured low-voltage characteristics and low- Available in VSSOP Package power dissipation make the LMC6482 especially well- suited for battery-operated systems. LMC6482 is also 2 Applications available in a VSSOP package, which is almost half Data Acquisition Systems the size of a SOIC-8 device.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
7 (3) Limiting Input pin current is only necessary for Input voltages that exceed absolute maximum Input voltage ratings. (4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150 C. Output currents in excess of 30 mA over long term may adversely affect reliability. (5) Do not short circuit Output to V+, when V+ is greater than 13 V or reliability will be adversely affected. (6) The maximum power dissipation is a function of TJ(max), R JA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) TA)/ JA.
